Patent FI-92760-C (FI)
Inventor: BENELLI PAOLO
IPC: F41A9/72
Filed: 1988-03-10
Granted: 1994-12-27
Abstract: The present invention relates to smooth-bore guns having a tubular magazine and an operating system either semiautomatic indifferently of the inertial type, of the gas intake type or of the recoiling barrel type, or manual pump-operated or convertible from one system to the other, relating essentially to a new cartridge feed system adapted to these types of firearms. The invention comprises a new cartridge descent lever (1) which causes the cartridges (15) to pass from the magazine tube (16) into the barrel (22), either automatically or manually. For the feeding with semiautomatic operation of the firearm, part of the energy of the spring of the hammer (18) of the firearm is used to cause the vertical rotation of the cartridge descent lever (1) so that a cartridge (15) exits from the magazine tube (16). For the feeding with manual pump operation of the firearm, the same movement is caused by the bolt (31) when it opens manually, by means of the cocking rod, for the expulsion of the case in the barrel (22). Finally, for the manual change of the cartridge (15) in the barrel (22) the same movement can be caused by the hand of the shooter which, with the finger which presses the trigger (17), finds, in an easily accessible position, a tab (44) of the cartridge descent lever (1) protruding from the lower level of the body of the firearm. In all the cases described above, the successive passage in the barrel (22) of the cartridge (15), exiting from the magazine tube (16), occurs in a conventional manner for the type of firearm considered. In the various operating systems all the movements of the new cartridge descent lever (1) are in any case synchronized and compatible with the used operation without the need for adjustments.

Inventor: LEMMER HELMUT
IPC: H01H50/54
Filed: 1980-10-30
Abstract: In a switch, in particular a power, control or starter switch, a contact system and a magnetic system are provided in a housing whereby the magnetic system actuates the contact system. The contact system is provided with contact bars having rigid contact pieces, as well as actuable bridges with movable contact pieces which are actuated by means of a common bridge, whereby each bridge and the associated contact bars are mounted in a switch chamber. Furthermore, a switch-on contact with a self-locking contact is provided. In switches of this type, it is typically required to hold a switching operation for a longer time period, without necessitating the manually pushing down of a push key. The required separate switch-on contact is typically mounted in a separate large housing. In order to reduce the structural and space requirements and to permit a simple wiring, a contact yoke is structurally integrated with the switch for the switch-on contact which can be actuated from the outside by means of an actuating element and which cooperates with the common bridge support.

IPC: H01H5/18
Filed: 1983-12-23
Abstract: A constant load and constant contact force snap-action switch (Figure 1) having a normally-closed movable operate contact (18) on a flipper blade (20) which has a compression strip (20c) that snaps through an S-curvature to a reverse buckled state to trip the operate contact open. The flipper blade is coupled through an insulating cap (26) to the leaf spring mounted movable alarm contact (22) to close the latter at the same time. A return spring (36) biased reset lever (32) resets the operate contacts on depression down a first amount, opens the operate contact without closing the alarm contacts on depression down a second amount for stop purposes, and trips the operate contacts open on lifting upwards for test purposes. On reset, lost motion in the coupling cap (26b) knocks the alarm contact open if welded. A selector (38) is settable to select any of three functions for the reset lever, (1) reset-stop-test, (2) auto reset stop, or (3) reset test.

Abstract: ABSTRACT OF THE DISCLOSURE      A flame resistant to nonflammable composite panel is produced from a nonextrudable core mixture with a pourable, nonflammable filling material and a binder, and on both sides cover strips, flexibly bonded to the core.  For a continuous production of the composite panel in one operation, the core mixture is poured onto a flexible lower adhesive film, supported as it runs in, and a pile extending over the entire width forms there.          Between the lower adhesive film and a flexible upper adhesive film, likewise supported as it runs in, material of the core mixture is continuously and uniformly drawn through a V gap and compacted there for the first time and calibrated to thickness.  The adhesive films containing the precompacted core mixture are adhesively bonded to the continuously fed cover strips.  The apparatus comprises a stretching roller for each of the adhesive films, a device for the uniform application of the core mixture, first means for forming a settable running-in angle and the V gap, second means for supporting the lower adhesive film and third means for the concluding pressing and heating, as well as a device for cutting to length.

Abstract: The present invention relates to pharmaceutical compositions for preventing excitatory amino acids neurotoxicity comprising as active ingredient (3S,4S)-tetrahydrocannabinol (THC) type compounds of general formula (I), as hereunder defined.        The compositions of the present invention are particularly effective in alleviating and even preventing glutamate neurotoxicity due to acute to the central nervous system (CNS), such as injuries due to prolonged seizures, compromised or reduced blood supply, deprivation of glucose supply and mechanical trauma. The present compositions may also be effective in alleviating other damages to the CNS like poison-induced convulsions, considered to be associated with amino acids receptors other than that of glutamate, for example glycine.        The compositions of the present invention are also effective in the treatment of certain chronic degenerative diseases which are characterized by gradual selective neuronal loss. In this connection, the compositions of the present invention are contemplated as therapeutically effective in the treatment of the Alzheimer's disease.        The present compositions are of special value in grand mal seizures, global hypoxic ischemic insults, in hypoxia, alone or in combination with blood flow reduction (ischemia) as well as in cases of cardiac arrest and in cases of abrupt occlusion of cerebral arteries (stroke).      Some of the compounds according to formula (I), as will be hereinafter described in detail, are novel compounds and are claimed as such within the scope of the present application.      The active ingredient of the pharmaceutical compositions according to the present invention is a compound of the general formula;    having the (+)-(3S,4S) configuration, wherein A----B designates a 1(2) or a 6(1) double bond, R designates CH3 or CH2OH, R1 designates a hydrogen atom or a lower acyl group, and R2 designates (A) a straight-chained or branched C6-12alkyl radical; or (B) a group -O-R3, in which R3 is a straight-chained or branched C5-9alkyl radical or a straight-chained or branched alkyl radical substituted at the terminal carbon atom by a phenyl group.      Compounds of formula (I) in which R designates CH2OH and R1 designates a lower acyl group are novel compounds.

IPC: B41J2/415
Filed: 1991-03-26
Granted: 2000-02-08
Abstract: A method and apparatus provide enhanced longevity of the ion cartridge in an MIDAX* (silent electric discharge) electrostatic imaging processing system. The conventional ion cartridge comprises a solid dielectric with driver and control electrodes on opposite sides, the second electrode defining a discharge region at the junction of the edge surface of the solid dielectric member. Alternating current is supplied to the electrodes to induce charged particle production electrical discharges. Gas is supplied to the discharge region to replace the vast majority of the air during charge particle generation. The gas is a mixture consisting essentially of nitrogen with an amount of argon, neon, xenon, or krypton effective to provide a catalyst for nitrogen ionization while preventing arcing. Typically, the gas is a mixture of nitrogen and argon in a ratio of about 5 to 1 to about 20 to 1 (e.g. about 10 to 1), with the total gas flow rate to the discharge region about 4.75 - 6.25 cubic feet per hour. The gas is supplied to the area between the ion cartridge and an imaging drum by a pair of gas manifolds at opposite ends of the drum, and a pair of spray tubes having numerous perforations along their length extending between the gas manifolds.      Regulators precisely control the amount of nitrogen and argon supplied to the gas manifolds.
